============================
What is DevOps & Why DevOps
============================

DevOps = Development + Operations

=> DevOps is a culture

=> DevOps is a process

=> DevOps means set of best practices.

=> DevOps is used to establish colloboration between dev team & ops team.

=> The main of devops process is used to simplify & automate & speed up application build & deployment process with high quality.

=> We can delivery application to client quickly by following devops practices

==========================================
How to adopt devops culture in project ?
==========================================

=> By using set of tools we can adopt DevOps culture in our project. Those tools are called as DevOps tools.


**** Infrastructure setup

	Ex: Machines, Database, Security, Storage, Network, Backup etc...

=> Using Terraform we can automate infrastructure setup in project.	


**** Configuration Management

	Ex: install softwares, os updates, transfer files etc...

=> Using Ansible we can automate configuration management


**** Source Code Management

=> All the developers code should be integrated at once place with tracking.

=> We can use GIT Hub or BitBucket or Git Lab as source code repository servers.


*** Project Build Process

=> Convert project source code into executable format

	.java programs  -------------> jar or war

	.csharp program --------------> dll file


=> We can use Maven or Gradle to build java projects

=> We can use MS Build to build Dot Net projects

=> We can use npm to build angular or react projects	

Note: Python is scripting language build process not required.


**** Artifactory Servers

=> To store project build artifacts like jars, wars, dlls

=> We can use Nexus or JFrog to store project artifacts.


**** Code Review

=> To identify developer mistakes in source code we will perform Code Review.

=> We can use SonarQube to perform project code review.


**** Application Deployment

=> To run application server is required

	Ex: 
		Tomcat server (java)
		IIS (.net)
		Nginx (angular or react)

Note: We will use Docker & Kubernetes for application deployment.

**** Automate Build & Deployment (CI CD)

=> Continuous Integration & Continuous Deployment

=> We can use Jenkins to implement CI CD in the project.


**** Monitoring

=> Servers Monitoring

Note: Using Promethues & Grafana we can monitor our servers

=> Application logs monitoring

Note: Using splunk or ELK we can monitor application logs.


============================================================


1) Terraform

2) Ansible

3) Git Hub / BitBucket / GitLab

4) Maven / Gradle / MS Build / NPM

5) SonarQube

6) Nexus / JFrog (artifacts upload)

7) Tomcat / IIS / Nginx

8) Docker

9) Kubernetes (K8S)

10) Jenkins (CI CD)

11) Prometheus & Grafana

12) Splunk / ELK


======================================================

## Step-1 : Setup Infrastructure for the project

		a) On-Premise Infrastructure (costly and risky)

		b) Cloud infrastructure

Note: Now a days companies are using Cloud Infrastructure.

## Step-2 : Configuration Management

## Step-3 : Manage source code repositories & RBAC (Role Based Access) for team members

## Step-4 : Automate Build & Deployment process (CI CD)

## Step-5 : Monitoring

=============================
What is IT Infrastructure ?
=============================

=> To run a software company we need below resources

		a) machines
		b) network
		c) power
		d) storage
		e) backup
		f) security

=> The above resources are called as "IT infrastructure"

=> We can maintain infrastructure in 2 ways

	1) On-prem infrastructure

	2) Cloud infrastructure

==================================
What is On-Prem Infrastructure ?
==================================	

=> On-Prem means we need to purchase and we need to maintain our resources to run our business.

=> We have several challenges with On-Prem infrastructure

		1) Lot of money investement
		2) Lot of man power
		3) Scalability (increase / decrease)
		4) Availability
		5) Network issues
		6) Security issues

=> To overcome the problems of on-prem infrastructure companies are preferring Cloud Infrastructure.

===========================
What is Cloud Computing ?
===========================

=> The process of delivering IT resources over the internet on demand basis is called as Cloud Computing.

=> We have below advantages with cloud computing

	- No Advance payments

	- Pay as you go

	- Scalability

	- Availability

	- Security

	- Backup & Restore


================
Cloud Providers
================

=> The companies which are providing IT infrastructure based on pay as you go model are called as Cloud Providers.

1) Amazon (AWS)

2) Microsoft (Azure)

3) Google (GCP)


==============
What is AWS 
==============

=> AWS stands for Amazon webservices.

=> AWS providing cloud services from 2006 onwards.

=> AWS providing IT infrastructure based on "pay as you go" model.

=> 190+ countries using AWS cloud services to run their businesses.

=> AWS having global infrastructure.

=> AWS managing infrastructure using "Regions & Availability Zones" concept.

		Region = Location  

		Availability Zone = Data Center (Server Room)

=> As of today AWS having 36 regions and 114 Availability Zones.

		AWS Map : https://aws.amazon.com/about-aws/global-infrastructure/


Note: In INDIA we have 2 regions

		1) Mumbai (ap-south-1)

				ap-south-1a
				ap-south-1b
				ap-south-1c

		2) Hyderbad	(ap-south-2)

				ap-south-2a
				ap-south-2b
				ap-south-2c


========================
How to use AWS Cloud ?
========================

=> We can create free tier account in aws cloud for practice. 

Note: credit or debit card required for aws account creation.

@@@  Reference Video : https://youtu.be/xi-JDeceLeI?si=adjfQqwTcRstQODd

=> In AWS we have 200+ services. In those few are paid and few are free.

Note: If we use any paid service then bill be generated. AWS will not deduct bill amount from our card. There is no concept of Auto Debits in AWS platform.

=> AWS will send reminders for bill payment. If we don't pay bill then our AWS account will suspended.

Note: We can request AWS support team to make bill amount as zero for 1 or 2 times. AWS support team will provide free credits for practice.

===============
AWS Services
